Gary (and Laurie), is the entire texture blurry, or just certain areas?

  In Poser, a blurred area on the texture is often due to a sharply acutely angled poly, a needle-shaped "sliver", so to speak.  Often, this can be cured by spinning the edge(s) so as to re-organize the area into polygons which have gentler angles.  Selectively deleting an edge to combine two triangles into one quad will often help.

Another possibility is duplex geometry;  what appears to be a simple rectangle may actually be an N-gon because one of the vertices is doubled.  This can happen after doing bevel/inset operations.  Just select all vertices, note the vertex count, and then use the merge command.  Did the vertex count decrease?  If so, you just fixed some duplex points. 
Doubled points -and overlapping/doubled polys- can also cause "shadowed" areas.
